Abstract (en)
[origin: WO2015169870A1] The present relates to a method of making a prosthetic valve that can take a first form wherein the valve is open and a second form wherein the valve is closed, the valve comprising a leaflet, a supporting element, and a stent to which the leaflet and supporting element are attached, the leaflet having a free margin that can move between a first position wherein the valve takes the first form and a second position wherein the valve takes the second form, the method comprising: - providing a woven textile structure, - forming the leaflet and the supporting element from this textile structure, such that a selvedge of the textile structure forms the free margin of the leaflet, and - forming the valve therewith, wherein the textile structure has a single layer thickness of between 40 to 150 μm and comprises yarn comprising polymeric filaments, the yarn having a linear density of less than 120 dtex and an elongation at break of 10% or less, and wherein the leaflet is attached to the stent by making stitches through at least 2 layers of the woven textile structure to form a commissure. The woven fabric used method is thin and flexible, and allows stitching through multiple layers to result in durable performance of both leaflets and commissures in actual use. The invention also relates to a prosthetic valve as obtainable by said method.
